Synthesis of sweet-tasting methylthio derivatives of D-fructose and sucrose.
Gan,Whistler,Daniel
, p. 45 - 51 (1990)
1,6-Di-S-methyl-1,6-dithio-D-fructofuranose and its bis(S-oxide) and bis(S,S-dioxide) are described. On examination for sweetness, the oxygenated compounds were neutral but the parent compound was 15-20 times sweeter than sucrose, and 1',6'-di-S-methyl-1'
